Zig Zag Pencil
You show a pencil in a plastic case. You can remove the pencil and hand it out for inspection.
With one swift move you break the pencil into three pieces.
The three pieces can be removed and handed out for inspection too.
Another swift move and the pencil is restored.
A very visual yet very easy to do trick that a five year old can master
in under a minute but fools adults too!
Comes with full instructions.
